Sang-Chul Role

Since the last fp episode, I’ve been curious. What is Sang-Chul’s role from here? Because back during the Christmas dinner, he was really quiet. Even when Kousuke and his brother were at each other’s throats, he didn’t say anything, not even in his brother’s defense. And here (spoiler alert) >!When Yui and Gun were talking about him, Sang-Chul eavesdropping and didn’t say anything either.!<

My question is, what do you guys think Sang Chul will do for the remainder of the season (or the time skip). Is there some possibility of Character Development, or is that a dumb idea?

Me personally, I kinda would like to see some character development, however at the same time, knowing what Sang Chul planned on doing to Shin-ae back at the Formal, it would be… odd to give him redeeming qualities, especially after that.

Remember Bryce Walker from 13 reason why? Yeah, that “redeeming quality” fell flat on his face, and he ended up dead anyway.
